I've had a massage a few days ago with a protected blow job. Before putting on a condom, she sucked my balls and licked my penis from bottom to nearly the end of my foreskin once. Is there risk of STDs? I know that protected blowjob is no cause for concern but it is what happened before that worries me. She has only licked the shaft of my penis once and her tongue did not touch anything beyond my foreskin before the protected blow job.
